本文研究了触发器直接置位复位端的各种应用。提出了在时序工作中置位复位端作用的理论,陈述了邻控原理,并发展了邻控式计数器的设计方法通。过8421BCD码加法计数器以及单脉冲发生器的设计,证明了采用邻控式置位复位的时序系统的线路比较简单,从而表明采用邻控式置位复位的时序系统设计方法具有一定的优点与实用意义。 This article studies various applications of the flip-flop directly to the reset terminal. The theory of setting the reset terminal in the timing work is presented, the adjacent control principle is stated, and the design method of the adjacent control counter is developed. The design of 8421BCD code addition counter and single pulse generator proves that the circuit of the timing system with the adjacent control reset is relatively simple, which shows that the method of timing system design with the adjacent control reset has some merits and practicalities significance.
